CBS News made it official Monday morning, revealing that Norah O’Donnell would become anchor and managing editor of the “CBS Evening News.” She will take over from Jeff Glor, who has helmed the program since December 2017 and whose future at the network remains uncertain.

“It is incredibly humbling to accept this position,” O’Donnell said on set at “CBS This Morning” Monday where she currently serves as a co-anchor. “I don’t stand on the shoulders of my colleagues, they carry me on their backs.”

O’Donnell is expected to formally take the anchor’s chair over the summer and the show will move from New York City to Washington, D.C. In addition O’Donnell will serve as the network’s lead anchor for political coverage and a contributing correspondent for “60 Minutes”

The news leaves Jeff Glor’s future at the network uncertain. In a statement on Monday, new CBS News president Susan Zirinzky said, “We are discussing opportunities for Jeff to remain with CBS News and continue providing the same substantive, trusted reporting that he has been offering for the past 12 years.”

On air, Gayle King called Glor a “fantastic journalist and trusted colleague.”

Additionally, the network confirmed that John Dickerson would be leaving “CBS This Morning” for a new gig as a correspondent on “60 Minutes,” and that Gayle King would remain at the show with new hosts, Tony Dokoupil and Anthony Mason.

The announcements confirmed speculation which leaked from the building last week that big changes were afoot at the network as Zirinsky looks to shake up a dire ratings picture across nearly every major program at CBS News as well as a workplace culture that has been rocked by a series of #MeToo scandals involving top executives, including ousted former network CEO Les Moonves.
